Halloween time is drawing near, houses are decorated with fake ghosts and spiderwebs, and children are preparing their perfect trick-or-treating costumes. But humans aren't the only ones who know how to celebrate the spooky season.

9. And, Sadly, Ghost Nets

Some of the most prevalent ghosts in the sea are also the scariest. Ghost nets are discarded fishing gear.

According to NatGeo, these forgotten nets, fishing lines and ropes drift along in the water, entangling and suffocating sea turtles, fish, dolphins, whales, sharks, coral and more. And there are so many of these lost nets poised to hurt our sea life.

NatGeo reported that 1.28 billion pounds of netting is lost every year. Plus, of all theplastic trash in the sea, 10 percent is made up of fishing gear.
